###  ehcache.xml
	<cache name="cache4Result"
           maxElementsInMemory="10"
           eternal="false"
           timeToIdleSeconds="3600"
           timeToLiveSeconds="10000"
           diskPersistent="true"
           overflowToDisk="true"
            />
### 	
	<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"/>
    <!-- 配置一个简单的缓存工厂bean对象 -->
    <bean id="simpleCache" class="org.springframework.cache.ehcache.EhCacheFactoryBean">
        <property name="cacheManager" ref="cacheManager"/>
        <!-- 使用缓存 关联ehcache.xml中的缓存配置 -->
        <property name="cacheName" value="cache4Result"/>
    </bean>
	<bean id="cache4ResultAspect" class="com.depan.Cache4Result.aspect.Cache4ResultAspect">
		<property name="cache" ref="simpleCache"/>
	</bean> 
     
     <aop:config>
        <aop:aspect id="myaspectj" ref="cache4ResultAspect">

		...

		/**
		*  cacheKeyName cache的key的名称
		*  liveSecond 缓存的存活时间 0 或不写表示 默认ehcache.xml 中的配置
		*
		* @param department 
		* @result list
		*/

		@Cache4Result(cacheKeyName = "findUsersByDepartment_${department.id}_${department.name}" , liveSecond = 60*60 )
		public List<User> findUsersByDepartment(Department department){
